Answer: They will have equal final angular velocity.
Explanation:
Since the discs starts from rest and rotates about a fixed axis, they are subject to a constant net torque. The work done by the torque during the second revolution is as the work done during the first revolution.
The four disc will turn through equal angles in equal times.
Answer:
5 ft/s²
Explanation:
u = Initial velocity = 100 ft/s
v = Final velocity = 0
s = Displacement = 1000 ft
a = Acceleration
From equation of motion
The airplane's deceleration is 5 ft/s² or 1.524 m/s²
Answer:
